Background: The coronavirus disease 2019 (COVID-19) among health care workers (H.C.W.s) in China have been contained
rapidly. Here, we report the results of a descriptive, exploratory analysis of all HCWs cases diagnosed during the outbreak and the
containment of the epidemic.
Methods: All COVID-19 cases of HCWs reported through Jun 2, 2020, were extracted from the Chinese Red Cross Fund (CRCF)
website. Analyses included the following: 1) summary of patient characteristics; 2) examination of sex ratios and age distributions; 3)
calculation of case fatality and mortality rates; 4) comparison between physician and nurses; 5) epidemiological curve construction; and
6) employment setting (the hospital; community health center; clinics). The 111 HCWs with COVID-19 reported by CRCF from June 3 to
November 22 were not included in this analysis.
Results: A total of 3,623 HCWs were diagnosed with COVID-19 across mainland China, and 31 of them died (0.9%). Among the
3,623 HCWs, most were female (70.7%), nurses (49.9%), diagnosed in Hubei (98.8%), and in January and early February 2020 (81.9%).
The epidemic curve of diagnosis peaked on Jan 23, 2020, which was three days after Chinese law’s amendment categorizing COVID-19
as a Class B notifiable disease and three weeks earlier than the peak time in the general population. With sufficient and rigorous
protection, the curve declined rapidly after early-February.
Conclusion: Rapid containing COVID-19 among HCWs in China is shared in the hope of ensuring the health and safety of HCWs
worldwide.
